' FLOAT.

To all whom it may concern.-

Be it known that I, ALEXIS IwANov PoLr- ANSKY, a subject of the Emperor of Russia, residing a 158 Newsky Prospekt, St. Petersburg, in the Empire of Russia, have invented a new and useful Improvement inFloats, of

which the following is-a specification.

My invention relates toinflatable floats, and has for its object to provide the same above and below along the longitudinal and trans- 5 tute rafts. floating bridges, or the like.

In the accompanying drawings I have represented a constructional form of my said invention, Figure 1 showing a collapsed float. and Fig. 2 showing an inflated float ready for This float consists of a prismatic rubber balloon or receptacle, Fig. 2, inclosed in a strong water-tight linen covering and provided with a valve a, through which air may be blown Whenthe balloon, the construction of which presents no novel features, is not inflated, its ends may be bent inward and its sides outward or the sides inward and the ends outward, so that the upper wall will lie di-.

3 rectly upon thelower wall.

In this state the balloon occupies as little space as possible and is adapted for transport, Fig. 1. Along the upper and lower longitudinal and transverse edges of this float I fix several loops b and turn-buttons a .or like fastening devices by means ofbands d, sewed onor otherwise. Any number of floats furnished in this man 'ner with loops and turnfbuttons or the like may thus be easily and instantaneously con- Specification of Letters Patent.

nected with each'other, the floats adjoining the sides and ends. By this means bridges,

rafts, or other floating appliances may bev '40 either at the sides-or at the ends, or both at.

and width which one man can inflate without any difliculty has a carrying power of about ,two hundred to two hundred and fifty pounds.

Having regard to the convenient transport and easy connection of the floats with each other for the various applications, these floats are particularly suitable for military pur' poses in countries which are destitute of wood or inthe case of insufficient communications.

What I claim as my invention, and desire to secureby Letters Patent, is-

1. In a device of the character-described, the combination, with two inflatable balloons, of cooperating loops and turn-buttons fastened along the upper and lower longitudinal v and transverse edges of the same, substantially as and for the purpose herein set forth. 2. .In a device of the character described,

the'combination with two balloons, of loops 6 and turn-buttons 0 attached to said balloons in such positions as to. cooperate with each other, and bands for securing said loops and buttons in place. v

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
